METHOD OF REDUCING TABBING VOLUME REQUIRED FOR EXTERNAL CONNECTIONS

摘要

Various embodiments are described herein for an electrode assembly for a stacked-cell battery. The electrode assembly comprises a first active material layer; a first current collector layer adjacent to and in electrical contact with an outer surface of the first active material layer; a tab element having an end lead portion and a second lead portion, the end lead portion being in electrical contact with at least one of the first active material layer and the first current collector layer, and the second lead portion extending away from the end lead portion and being substantially adjacent to a surface of at least one of the first active material layer and the first current collector layer and is adapted to provide an electrical connection to the electrode assembly; and an insulative layer covering an inner contact area of the second lead portion to electrically insulate this portion of the tab element.
